Using Codex via the ChapGPT mobile app while out and about this weekend. It’s controlling Codex on a Mac Mini, which is building a native iPhone app. I’m just texting it feedback and it’s sending me fresh TestFlight builds. Wild times!
For every lazy hater saying AI is useless and over-hyped there is a real person making their life tangibly better using AI… choose your team.
Be the broccoli farmer.
Codex can now deploy and host websites for you using Sites! 🎉
This includes storage for data and files using D1 and R2 💥
We started rolling out to Business and Enterprise customers before rolling out more broadly.
More details 👇
The Codex usage limits have been reset for all paid ChatGPT subscriptions. You should be back to 100% weekly and 100% hourly limits.
Let the tokens do incredible things today and have fun.
we shipped a new version of gpt-5.5 instant today. the previous model was too bullet pilled. the new one improves on some other important dimensions: sycophancy, factuality, and multilingual performance. hope you'll like it! always interested in feedback
I'm genuinely blown away by the state of using AI for marketing and general tasks.
This is a screenshot from codex. The right side of the screen is Notion open in the in app browser. Always signed into my account.
When the agent creates a notion doc (Codex has it's own notebook in my notion) it sends me a link.
I right click that link and select "Open in Browser" this opens the link on the right.
I can make changes, that the agent can see.
The agent can make changes that I can see.
The browser now persists... meaning when i sign into an external app in the browser I stay signed in, even in new chats.
Codex not only can plugin to my existing tools, but it can open my existing tools INSIDE CODEX.
This update to Codex is 10x more important than any marginal improvement to the models.
I don't understand why more people aren't talking about this. I don't mean to sound like a broken record, but if you use this workflow a few times it becomes obvious that this is the future of work.
Every bug in @ChatGPTapp is getting fixed
With the help of codex (and the rest of the lovely team and their codexes) along with a 7pm iced americano there will be zero bugs
This is a formal request for tiny nits, error states, broken ui, etc
The tinier the better!
good news: /goal in codex has solved all my problems
bad news: i'm sitting here twiddling my thumbs while the agents do all my bidding
it's no secret i'm a little bit obsessed with codex, and /goal is a big part of that.
i put together a 30m ep on /goal including:
- what it is
- how to write a good goal
- how to drive bug zero with @vercel@sentry and codex
- two non-technical use cases for goal, including cleaning up 4,000 emails over 4 hours

so Codex on iPad acts like a Codex mobile phone, which gives you the full desktop UI/UX. meaning, you can use your iPad to control your mac mini at home and have full screen portable development, it's really magical.
I've had more "I can't believe it's this good" moments with GPT5.5 than any other model since Opus 4.5. It's shockingly, scarily capable. Days and days of amazing progress. All steering, no handwriting. Yet utterly delightful to conduct its coding. So, so good.
For complicated agent work, it's amazing how much GPT5.5 has improved. I found 5.2 to be very far behind Opus. Now using Opus 4.7 after 5.5 feels like a big step backwards. Gotta love this level of competion! Strong comeback for OpenAI.
This is the biggest deal in the history of AI so far. And it will look like a small deal at the end of the year.
I’ve spent countless hours on this problem as a PhD student. I genuinely cannot believe I’m alive to watch AI solve it.
AI generating new knowledge and accelerating science will change the trajectory of humanity.
And we are unbelievably early.
Honestly I'm still really impressed with the Codex app.
It works reliably. It adds useful features consistently. It has taste. The mobile integration is awesome. The git integration is solid.
If you haven't used it yet, I highly recommend it.
